Agree. Investing in your employee to teach them the complete industry is not what I would choose.
Another reason why NOT: they might say goodbye and offer their own link building services to your competition...
Slightly off topic but staff retention isn't a problem in this scenario - it's a large company that invests in its staff precisely so they don't feel like they could be doing better at its competitors.
Anyway anybody with any sort of drive and passion about their work is going to be able to teach themselves pretty much everything there is to know about link building in their spare time. Why not formalise that, guide it and make sure that you're both reading from the same page?
